External Email - Use Caution
I should maybe add some more info to the last email:
* The error is not subject-specific. I tried for all my subjects, and the error is identical for all of them. * I am aware of the face that one needs Matlab to run lGI, and it is on the PATH (otherwise the lGI computation for the cross subjects would also fail). * I know that the error message, on first glance, seems to suggest that there is a syntax error in the recon-all shell script, and that this may suggest that someone messed with it. I strongly believe that this is not the case though, because: 1) FreeSurfer is installed in a directory where only root has write access. 2) The cross subject lGI computation finished successfully this morning. 3) Running 'stat' on the recon-all file shows that it has not been modified after the installation data, more than a year ago.
If you want me to upload subject data, please let me know.
Best,
Tim

Dear FreeSurfer experts,
I am trying to compute local lGI in FreeSurfer 6 for a subject that has undergone longitudinal processing.
In this example, the longitudinal base subject folder (with the long template recon-all output for that subject) is called "111002" and the folder with the data for timepoint 1, for which I would like to compute lGI now, is called "111002_MR1.long.111002". So I run the following command:
recon-all -long 111002_MR1.long.111002 111002 -localGIThe only output, after less than a second, is:
Unmatched '"'.Then the script terminates and I am back at the shell. Any thoughts on this or ideas?
I have successfully computed local lGI for the cross subjects on the same computer, it finished this morning (using the command 'recon-all -s $CROSS_SUBJECT -localGI'). So the recon-all command in general seems to work, the error is specific to the lgi long command it seems.
Here is some system info:
cat $FREESURFER_HOME/build-stamp.txt

All the best,
